Hello,
We have a low-criticality storage need in our datacenter, and the current solution has been letting us down so I wanted to give TrueNAS a spin.
The hardware is a PowerEdge 7415 running AMD Epyc 7402P with 256GB RAM. There is no storage controller other than the Dell BOSS boot storage, which is a 2-SSD boot RAID card. All of the other storage are Micron 9300 Pro NVMe hanging off of the PCIe bus.
I understand that usually TrueNAS discussions start with "use an LSI HBA", but that's not really an option when dealing with a dozen PCIe x4 SSDs. My understanding is that the entire point of the HBA is simply to provide an un-messed-around-with view of the disk to the underlying ZFS.
My hope is to set the BOSS card as the boot device, and configure the dozen NVMe as either a single 12-disk RAIDz2 or a pool of 6 mirror vdevs with no SLOG. Our IOP requirements are probably under 100k, which I'm hoping shouldn't be an issue given that each NVMe typically benchmarks ~150k write and ~900k read.
Is there any reason this would not work, or have poor performance?
Thanks!
